| Where
do char occur?
Arctic
Char in Ireland
All
Irish populations are confined to freshwater lakes, although in more
northerly countries they migrate to sea in a similar manner to salmon.
Most
populations occur in deep mountain lakes in the west from Donegal to
Kerry, e.g, L.Eske (top) and L. Coomasaharn (bottom).
Into
the last century populations existed in the midlands and along the east
coast, but all of these are now probably extinct.
World
Wide Distribution
The
arctic char has the most northerly geographic distribution of any freshwater
fish. The centre for distribution of arctic char in which it reaches
its maximum density is the frozen coastline of the Arctic Ocean. The
southerly extent of their range approximates that of the extent of winter
sea ice, roughly between 64° and 65° N.
Arctic char are at the extreme limit of their southerly distribution
in Ireland.
The
Arctic Circle
Arctic
char from the arctic circle display the most dramatic colors during
the spawning season. The male char (bottom) is in typical spawning livery.
These
fish would have fed at sea among the icebergs of the high north. Here
they form an important part of the diet of the the Innuit.
Arctic
Char in Europe
Arctic char in Europe are also under threat. In the past few decades
more char populations have been lost to pollution and development than
in the previous centuries. This makes the remaining populations all
the more valuable and vulnerable. Unfortunately, there are few projects
in these countries which aim to protect their remaining populations
of char.
